Real time multiplayer work for me well enough on a regional bases. I don't know where the myth that TCP can't do real time, but it's nto true. UDP is far better for realtime, but TCP can still work. Age of Empires was Realtime. Guildwars, WoW both use TCP for PvP. Is it as good as Call of Duty Counter strike. No, it's not. but the word "can't" or "technically not doable" is not applicable.
Hese a demo of TCP game
There is no advance client prediction or dead reckoning. So if the latenency is bad enough characters will make a small jump. That's easily fixable by a better movement engine. The sample never intended to be good. just show the viabliity of WebSockets for real time game.
To me it's a success :)
